Postpartum infections and antimicrobial resistance of responsible pathogens in Ukraine: results a multicenter study (2020-2022).

OBJECTIVE: Aim: To determine the current prevalence of postpartum infections and antimicrobial resistance and antimicrobial resistance of responsible pathogens in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter prospective cohort study was conducted from January 2020 to December 2022 in fifteen hospitals from twelve regions of Ukraine. Definitions of healthcare- associated postpartum infection were adapted from the Centers for Disease Control and Prevention's National Healthcare Safety Network. Antibiotic susceptibility was done by the disc diffusion test as recommended by EUCAST. RESULTS: Results: Among 21,968 women, 6,175 (28.1%) postpartum infections were observed. Of all postpartum infection cases, 83.1% were detected after hospital discharge. The postpartum infection rates were 17.3% after cesarean section and 10.8% after vaginal delivery. The most common postpartum infection types were endometritis (17.3%), followed by urinary tract Infection (3.5%), mastitis (3.4%), surgical site infection (excluding endometritis) (2.4%), and episiotomy site infection (1.5%). The predominant postpartum infection pathogens in Ukraine were: Escherichia coli (10.4%), Enterococcus spp. (9.6%), Staphylococcus aureus (6.7%), Pseudomonas aeruginosa (5.8%), Enterobacter spp. (5.8%). In our study pathogens of postpartum infection had differently levels of resistance to antibiotics. CONCLUSION: Conclusions: Our results indicate that postpartum infections requiring medical attention are common in Ukraine and that most postpartum infections occur after hospital discharge, so that use of routine inpatient surveillance methods alone will lead to underestimation of postpartum infection rates. Optimizing the antibiotic prophylaxis may reduce the burden of postpartum infection, but prevention is the key element.

Can the use of azithromycin during labour reduce the incidence of infection among puerperae and newborns? A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: This systematic review and meta-analysis investigated whether the use of azithromycin during labour or caesarean section reduces the incidence of sepsis and infection among mothers and newborns. DATA SOURCES: We independently searched the PubMed, Web of Science, Cochrane Library and EMBASE databases for relevant studies published before February, 2024. METHODS: We included RCTs that evaluated the effect of prenatal oral or intravenous azithromycin or placebo on intrapartum or postpartum infection incidence. We included studies evaluating women who had vaginal births as well as caesarean sections. Studies reporting maternal and neonatal infections were included in the current analysis. Review Manager 5.4 was used to analyse 6 randomized clinical trials involving 44,448 mothers and 44,820 newborns. The risk of bias of each included study was assessed using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions.Primary outcomes included the incidence of maternal sepsis and all-cause mortality and neonatal sepsis and all-cause mortality; secondary outcomes included maternal (endometritis, wound and surgical site infections, chorioamnionitis, and urinary tract infections) and neonatal outcomes (infections of the eyes, ears and skin). A random-effects model was used to test for overall effects and heterogeneity. RESULTS: The pooled odds ratios (ORs) were as follows: 0.65 for maternal sepsis (95% CI, 0.55-0.77; I2, 0%; P < .00001); 0.62 for endometritis (95% CI, 0.52-0.74; I2, 2%; P < .00001); and 0.43 for maternal wound or surgical site infection (95% CI, 0.24-0.78; P < .005); however, there was great heterogeneity among the studies (I2, 75%). The pooled OR for pyelonephritis and urinary tract infections was 0.3 (95% CI, 0.17-0.52; I2, 0%; P < .0001), and that for neonatal skin infections was 0.48 (95% CI, 0.35-0.65; I2, 0%, P < .00001). There was no significant difference in maternal all-cause mortality or incidence of chorioamnionitis between the two groups. No significant differences were observed in the incidence of neonatal sepsis or suspected sepsis, all-cause mortality, or infections of the eyes or ears. CONCLUSION: In this meta-analysis, azithromycin use during labour reduced the incidence of maternal sepsis, endometritis, incisional infections and urinary tract infections but did not reduce the incidence of neonatal-associated infections, except for neonatal skin infections. These findings indicate that azithromycin may be potentially beneficial for maternal postpartum infections, but its effect on neonatal prognosis remains unclear. Azithromycin should be used antenatally only if the clinical indication is clear and the potential benefits outweigh the harms.

Risk Factors, Trends, and Outcomes Associated With Postpartum Sepsis Readmissions.

OBJECTIVE: To evaluate the prevalence, timing, clinical risk factors, and adverse outcomes associated with postpartum readmissions for maternal sepsis. METHODS: We conducted a retrospective cohort study of delivery hospitalizations and 60-day postpartum readmissions for females aged 15-54 years with and without sepsis using the 2016-2020 Nationwide Readmissions Database. Temporal trends in sepsis diagnoses during delivery hospitalizations and 60-day postpartum readmissions were analyzed with the National Cancer Institute's Joinpoint Regression Program to estimate the average annual percent change with 95% CIs. Logistic regression models were fit to determine whether delivery hospitalization characteristics were associated with postpartum sepsis readmissions, and unadjusted and adjusted odds ratios with 95% CIs were reported. Adverse outcomes associated with sepsis during delivery hospitalization and readmission were described, including death, severe morbidity, a critical care composite, and renal failure. RESULTS: Overall, 15,268,190 delivery hospitalizations and 256,216 associated 60-day readmissions were included after population weighting, of which 16,399 (1.1/1,000 delivery hospitalizations) had an associated diagnosis of sepsis at delivery, and 20,130 (1.3/1,000 delivery hospitalizations) had an associated diagnosis of sepsis with postpartum readmission. A sepsis diagnosis was present in 7.9% of all postpartum readmissions. Characteristics associated with postpartum sepsis readmission included younger age at delivery, Medicaid insurance, lowest median ZIP code income quartile, and chronic medical conditions such as obesity, pregestational diabetes, and chronic hypertension. Postpartum sepsis readmissions were associated with infection during the delivery hospitalization, including intra-amniotic infection or endometritis, wound infection, and delivery sepsis. Sepsis diagnoses were associated with 24.4% of maternal deaths at delivery and 38.4% postpartum, 2.2% cases of nontransfusion severe morbidity excluding sepsis at delivery and 13.6% postpartum, 15.6% of critical care composite diagnoses at delivery and 30.1% postpartum, and 11.1% of acute renal failure diagnoses at delivery and 36.4% postpartum. CONCLUSION: Sepsis accounts for a significant proportion of postpartum readmissions and is a major contributor to adverse outcomes during delivery hospitalizations and postpartum readmissions.

Can Clean Delivery Kits Prevent Infections? Lessons from Traditional Birth Attendants in Nigeria.

Background: In resource-poor settings, perinatal infections contribute significantly to maternal and neonatal deaths, and the use of clean delivery kits (CDKs) has been proposed as a tool to reduce the risk of infection-related deaths. This study aims to assess the acceptability and effectiveness of CDKs in preventing infections in deliveries attended by traditional birth attendants (TBAs) in Abeokuta, Nigeria. Methods: The study was a cluster-randomized trial with 67 birth centres/clusters, 453 births/mothers, and 457 babies randomized to intervention or control arms; intervention involved supplementation of delivery with JANMA CDKs. Interviews were conducted at the birth homes, and the primary outcomes were neonatal infection and puerperal fever. The association between infection and perinatal risk factors was tested using the Chi-square and Fisher's exact tests. Results: CDKs were well accepted by TBAs. The incidence of puerperal fever and neonatal infection was 1.1% and 11.2%, respectively. Concurrent infection was found in 1 (0.22%) of the mother-neonate pair. There was no significant association between any of the sociodemographic factors and infection for both mothers and neonates. PROM and prolonged labour were significantly associated with puerperal infection. All mothers with puerperal fever were from the control group. Compared to the control group, the relative risk of puerperal infection and neonatal infection in the intervention group was 0.08 (0.004 -1.35, p = 0.079) and 0.64 (0.37 to 1.1, p = 0.10), respectively. Conclusion: CDKs hold promising results in attenuating maternal infections in resource-poor settings. Larger studies with greater statistical power are required to establish statistically reliable information.

Incidence, temporal trends and risk factors of puerperal infection in Mainland China: a meta-analysis of epidemiological studies from recent decade (2010-2020).

BACKGROUND: Puerperal infection (PI) is a severe threat to maternal health. The incidence and risk of PI should be accurately quantified and conveyed for prior decision-making. This study aims to assess the quality of the published literature on the epidemiology of PI, and synthesize them to identify the temporal trends and risk factors of PI occurring in Mainland China. METHODS: This review was registered in PROSPERO (CRD42021267399). Putting a time frame on 2010 to March 2022, we searched Cochrane library, Embase, Google Scholar, MEDLINE, Web of Science, China biology medicine, China national knowledge infrastructure and Chinese medical current contents, and performed a meta-analysis and meta-regression to pool the incidence of PI and the effects of risk factors on PI. RESULTS: A total of 49 eligible studies with 133,938 participants from 17 provinces were included. The pooled incidence of PI was 4.95% (95%CIs, 4.46-5.43), and there was a statistical association between the incidence of PI following caesarean section and the median year of data collection. Gestational hypertension (OR = 2.14), Gestational diabetes mellitus (OR = 1.82), primipara (OR = 0.81), genital tract inflammation (OR = 2.51), anemia during pregnancy (OR = 2.28), caesarean section (OR = 2.03), episiotomy (OR = 2.64), premature rupture of membrane (OR = 2.54), prolonged labor (OR = 1.32), placenta remnant (OR = 2.59) and postpartum hemorrhage (OR = 2.43) have significant association with PI. CONCLUSIONS: Maternal infection remains a crucial complication during puerperium in Mainland China, which showed a nationwide temporal rising following caesarean section in the past decade. The opportunity to prevent unnecessary PI exists in several simple but necessary measures and it's urgent for clinicians and policymakers to focus joint efforts on promoting the bundle of evidence-based practices.

Determinants of term premature rupture of membrane: case-control study in Saint Paul's Millennium Medical College Hospital, Addis Ababa, Ethiopia.

BACKGROUND: The term premature rupture of the membranes is the rupture of the membranes before the onset of labor beyond 37 weeks of gestation. Several factors, including obstetric, gynecologic, socioeconomic, and medical, are identified as potential risk factors. This clinical event has detrimental maternal and neonatal complications. OBJECTIVES: This study aimed to investigate the determinants of the term premature rupture of the membranes in Ethiopia. METHODS: This institution-based unmatched case-control study was conducted on 246 women admitted to Saint Paul's hospital millennium medical college from October 2019 to January 2020 (82 cases and 164 controls). Data were collected using an interviewer-based questionnaire and data extraction tools, and data were entered using Epi data 3.1 and analyzed using SPSS 20. The association between independent variables and premature rupture of the membrane was estimated using an odds ratio with 95% confidence intervals and P-value < 0.05. RESULTS: Factors like a history of vaginal discharge (AOR 3.508;95% CI:1.595.7.716), place of Antenatal care follow-up (health center and Mercy Ethiopia) (AOR 5.174;95% CI:2.165,12.362), the previous history of rupture of membrane (AOR 9.955;95% CI:3.265,20.35), and gestational age (AOR 3.018;95% CI:1.338,6.811) were associated with term premature rupture of membrane. There were more maternal and neonatal complications, including puerperal sepsis, wound infection, anemia/PPH, a hospital stays of more than seven days, clinical amnionitis, neonatal hypoglycemia, early onset neonatal sepsis, and respiratory distress encountered by women who presented with premature rupture of membrane. CONCLUSION: Proper screening, close monitoring, and early interventions in those mothers with identified risk factors would help to reduce its negative consequences. Moreover, the provision of continuous professional skill development and improving the quality of ANC service is needed.

Human CEACAM1 is targeted by a Streptococcus pyogenes adhesin implicated in puerperal sepsis pathogenesis.

Life-threatening bacterial infections in women after childbirth, known as puerperal sepsis, resulted in classical epidemics and remain a global health problem. While outbreaks of puerperal sepsis have been ascribed to Streptococcus pyogenes, little is known about disease mechanisms. Here, we show that the bacterial R28 protein, which is epidemiologically associated with outbreaks of puerperal sepsis, specifically targets the human receptor CEACAM1. This interaction triggers events that would favor the development of puerperal sepsis, including adhesion to cervical cells, suppression of epithelial wound repair and subversion of innate immune responses. High-resolution structural analysis showed that an R28 domain with IgI3-like fold binds to the N-terminal domain of CEACAM1. Together, these findings demonstrate that a single adhesin-receptor interaction can drive the pathogenesis of bacterial sepsis and provide molecular insights into the pathogenesis of one of the most important infectious diseases in medical history.

Estimating predictors of severity of group A Streptococcus infection in pregnancy.

OBJECTIVE: To identify the clinical characteristics of pregnancy associated group A streptococcus (GAS) infection and predictors for intensive care unit (ICU) admission. METHODS: A retrospective cohort study of culture-proven pregnancy-related GAS infections in tertiary hospital Electronic medical records were reviewed, for cases of cultures positive GAS that were identified between January 2008 and July 2021. A GAS infection was defined by the isolation of the pathogen from a sterile liquid or tissue site. Blood and urine cultures were obtained from all patients with peripartum hyperpyrexia (fever >38 °C). Medical Personnel screening included cultures of the throat, rectum, and skin lesions (if present). In cases of hemodynamic instability patients were transferred ad hoc to ICU, according to the obstetrician and intensivist judgment. RESULTS: Of the 143,750 who delivered during the study period, 66 (0.04%) were diagnosed as having a pregnancy associated GAS infection. Of these, 57 patients presented postpartum, and represented the study cohort. The most common presenting signs and symptoms among puerperal GAS, were postpartum pyrexia (72%), abdominal pain (33%), and tachycardia (>100 bpm, 22%). 12 women (21.0%) developed streptococcal toxic shock syndrome (STSS. Predictors for STSS and ICU admission were: antibiotic administration >24 h from presentation postpartum, tachycardia, and a C-reactive protein level >200 mg/L. Women that received antibiotic prophylaxis during labor had a significantly lower rate of STSS (0 vs 10, 22.7%; p = .04). CONCLUSION: Deferral of medical intervention >24 h from the first registered abnormal sign had the most important impact on deterioration of women with invasive puerperal GAS. Antibiotic prophylaxis during labor in women with GAS may reduce associated complications.

Antibiotic Prophylaxis to Prevent Obesity-Related Induction Complications in Nulliparae at Term: a pilot randomized controlled trial.

BACKGROUND: Women with obesity are at increased risk of complications during and after labor and delivery, including puerperal infection and cesarean delivery. As labor induction has become increasingly common, it is crucial to find ways to decrease complication rates in this high-risk population. OBJECTIVE: This study aimed to explore the effect of prophylactic antibiotics during labor induction of nulliparous women with obesity on the rates of cesarean delivery and puerperal infection and to estimate the parameters needed to calculate the sample size for a larger, multicenter trial. STUDY DESIGN: In this randomized, placebo-controlled pilot trial, nulliparous patients with a body mass index of ≥30 kg/m2 were randomized to either prophylactic antibiotics (500 mg azithromycin for 1 dose and 2 g cefazolin every 8 hours for up to 3 doses) or placebo, administered starting at the beginning of labor induction. The exclusion criteria were known fetal anomaly, fetal demise, multifetal gestation, ruptured membranes >12 hours, infection requiring antibiotics at the start of labor induction, and/or allergy to azithromycin or beta-lactam antibiotics. The co-primary outcomes were rates of puerperal infection (composite of chorioamnionitis, endometritis, and/or cesarean delivery wound infection) and cesarean delivery. Participants were followed up for 30 days after delivery, and maternal and neonatal demographic and outcome data were collected. Proportions and 95% confidence limits were calculated for each of these outcomes. RESULTS: From January 2019 to May 2021, 101 patients were randomized in the class III stratum (1 patient who was randomized ultimately did not undergo labor induction). From February 2020 to May 2021, 38 and 47 patients were randomized to class I and II strata, respectively (to assess the effect of obesity class on the outcomes expected to be influenced by antibiotic prophylaxis). In the antibiotics and placebo groups, the rates of cesarean delivery were 29.0% (95% confidence interval, 19.8-38.3) and 39.8% (95% confidence interval, 29.8-49.7), respectively, and puerperal infection occurred in 8.6% (95% confidence interval, 2.9-14.3) and 9.7% (95% confidence interval, 3.7-15.7), respectively. In the subgroup with class III obesity, in the antibiotics and placebo groups, the rates of cesarean delivery were 33.3% (95% confidence interval, 20.4-47.9) and 46.0% (95% confidence interval, 32.2-59.8), respectively, and puerperal infection occurred in 7.8% (95% confidence interval, 0.5-15.2) and 10.0% (95% confidence interval, 1.7-18.3), respectively. Note that this pilot study was not powered to detect differences of this magnitude but rather to estimate parameters. CONCLUSION: The administration of prophylactic antibiotics during labor induction of nulliparous patients with obesity resulted in a 27% lower cesarean delivery rate overall and a 28% lower rate in patients with class III obesity. A larger trial is warranted to evaluate these differences.

A twenty-first century perspective on concepts of modern epidemiology in Ignaz Philipp Semmelweis' work on puerperal sepsis.

We aimed to review Semmelweis's complete work on puerperal sepsis mortality in maternity wards in relation to exposure to cadavers and chlorine handwashing and other factors from the perspective of modern epidemiological methods. We reviewed Semmelweis' complete work and data as published by von Györy 1905 according to current standards. We paid particular attention to Semmelweis's definition of mortality in and of itself, to concepts of modern epidemiology that were already recognizable in Semmelweis's work, and to bias sources. We did several quantitative bias analyses to address selection bias and information bias from outcome measurement error. Semmelweis addressed biases that have become known to modern epidemiology, such as confounding, selection bias and bias from outcome misclassification. Our bias analysis shows that differential loss to follow-up is an unlikely explanation for his results. Bias due to outcome misclassification would only be relevant if misclassification differed between time periods. Confounding by health status was likely but could not be quantitatively addressed. Semmelweis was aware that cause-specific mortality is a function of incidence and prognosis. He reasoned in potential outcome terms to estimate the reduced number of deaths from an intervention. He advanced a hypothesis of clinic overcrowding as a risk factor for puerperal sepsis mortality that turns out to be wrong. Semmelweis' data provide a great pool for illustrating the logic of scientific discovery by use of the numerical method. The explanatory power of his work was strong and Semmelweis was able to refute several previous causal explanations.

Pre-Caesarean Section Vaginal Preparation with Chlorhexidine Solution in Preventing Puerperal Infectious Morbidities: A Randomized Controlled Trial.

BACKGROUND: Globally, peripartum or puerperal infections account for about one tenth of maternal mortality, most of which occur in low income countries. Therefore, vaginal preparation with an antiseptic prior to a caesarean delivery could be considered an additional measure to prevent subsequent infectious morbidities. OBJECTIVES: To evaluate vaginal preparation with 0.3% chlorhexidine solution in the prevention of endometritis, surgical site infection and post-operative fever following emergency caesarean section. METHODS: This prospective randomized controlled trial (RCT) was conducted among 240 participants planned for emergency caesarean sections (CS) at term in the University of Medical Sciences Teaching Hospital Complex, Ondo State, Nigeria. Participants were randomised into either group "A" (study) or "B" (control). The former had vaginal preparation with 0.3% chlorhexidine gluconate immediately after anaesthesia while the latter received normal saline. Participants were followed up post-operatively during which clinical features of puerperal infectious morbidities were observed for each during admission as well as 8th and 14th days after delivery. RESULTS: The rate and risk of endometritis were significantly lower in the study group compared to the control; 5.0% versus 13.3%, respectively (chi squared =5.004; p=0.042, RR = 0.38; 95% CI = 0.15-0.94; p = 0.042; RRR = 0.62). Post-operative fever and surgical site infection, were also lower in the study group compared to the controls, but the difference was not statistically significant. CONCLUSION: When compared to placebo, pre-caesarean section vaginal preparation with 0.3% chlorhexidine solution significantly reduced only the rate and risk of post-operative endometritis among infectious morbidities.

CONTEXTE: À l'échelle mondiale, infections péripartum ou puerpérales représentent environ un dixième de la mortalité maternelle, dont la plupart se produisent dans les pays à faible revenu. Par conséquent, la préparation vaginale avec un antiseptique avant un accouchement par césarienne pourrait être considéré comme un mesure supplémentaire pour prévenir les morbidités infectieuses subséquentes. OBJECTIFS: Évaluer la préparation vaginale avec 0.3%solution de chlorhexidine dans la prévention de l'endométrite, site chirurgical infection et fièvre postopératoire après une césarienne d'urgence section. MÉTHODES: Cet essai prospectif randomisé contrôlé (ECR)a été menée auprès de 240 participants prévus pour une urgence césariennes (CS) à terme à l'Université des sciences médicales Complexe hospitalier universitaire, État d'Ondo, Nigéria. Les participants étaient randomisé dans le groupe "A" (étude) ou "B" (témoin). Celui-là avait une préparation vaginale avec 0.3 % de gluconate de chlorhexidine immédiatement après l'anesthésie alors que ce dernier a reçu une solution saline normale. Les participants ont été suivis postopératoirement au cours desquels des caractéristiques de morbidité infectieuse puerpérale ont été observées pour chaquelors de l'admission ainsi que les 8ème et 14ème jours après la livraison. RÉSULTATS: Le taux et le risque d'endométrite étaient significativement plus faibles dans le groupe d'étude par rapport au groupe témoin; 5.0 % contre 13.3 %, respectivement (chi carré =5.004; p=0.042, RR = 0.38; 95% CI = 0.15­0.94; p = 0.042; RRR = 0.62). Fièvre postopératoire et infection du site chirurgical, étaient également plus faibles dans le groupe d'étude par rapport aux témoins, mais lela différence n'était pas statistiquement significative. CONCLUSION: Par rapport au placebo, pré-césarienne préparation vaginale avec une solution de chlorhexidine à 0.3% significativement réduit uniquement le taux et le risque d'endométrite postopératoire chez morbidités infectieuses. Mots-clés: Chlorhexidine, Préparation Vaginale, Infection Puerpéral emorbidité, Césarienne, Endométrite, Fièvre Postopératoire, Infection Du Site Chirurgical.

Prophylactic postoperative antibiotics after emergent cesarean delivery and risk of postpartum infection or wound complication.

BACKGROUND: Emergent cesarean delivery (CD) carries a high risk for postpartum infection. In cases with a "splash" povidone-iodine (PI) skin preparation, prophylactic postoperative antibiotics (PP-Abx) are sometimes utilized, but the benefit is unclear. OBJECTIVE: To evaluate if the use of PP-Abx decreases postpartum infection after emergent CD with "splash" PI skin preparation. STUDY DESIGN: Cohort study of patients undergoing emergent CD with PI skin preparation from July 2012 to April 2020 at a single institution. Cases were identified using a natural language search engine, DEEP-6, with key terms "emergent" and "cesarean delivery." Patients with chorioamnionitis or non-PI skin preparation (e.g. chlorhexidine) were excluded. The primary exposure was use of PP-Abx. The primary outcome was postpartum infection or wound complication, defined as a composite: endometritis, wound infection, cellulitis, seroma, hematoma, or intra-abdominal abscess. Rates of postpartum infection or wound complication were stratified by use of PP-Abx. Demographic and labor characteristics were evaluated as confounders. Statistics by χ2, t-test, and logistic regression (α = 0.05). RESULTS: In total, 481 patients underwent emergent CD; of those, 370 had PI skin preparation and were included. PP-Abx were given in 43% (160/370) of cases, including: cefazolin (n = 137), gentamicin/clindamycin (n = 18), azithromycin (n = 3), and vancomycin (n = 2). Those receiving PP-Abx were similar to those who did not, except the PP-Abx group was younger with longer CD duration. The rate of postpartum infection or wound complication was no different in patients who received PP-Abx compared to those who did not (12.6% vs. 9.5%, p = .34). This finding remained unchanged after multivariable adjustment (aOR 1.2, CI 0.61-2.4, p = .60). Moreover, the rate of postpartum infection or wound complication did not vary by antibiotic choice. CONCLUSIONS: After emergent CD with PI skin preparation, routine use of prophylactic postoperative antibiotics does not appear to reduce the rate of postpartum infection or wound complication, which is important as we consider antibiotic stewardship. More studies are needed to identify treatments that decrease infectious morbidity with emergent CD.

Factors Affecting Postpartum Infection: A Systematic Review.

BACKGROUND: Puerperal infection is used to describe any bacterial infection of the reproductive tract after delivery. Identifying the factors affecting postpartum infections can reduce the risk and complications of such factors and postpartum maternal mortality. OBJECTIVE: This structured study was designed to evaluate factors affecting postpartum infections. METHODS: In this study, after selecting Scopus, PubMed, SID, and Web of Science electronic databases, all observational studies (cohort and case-control) available and published in Farsi and English to investigate factors affecting postpartum infections were searched. The search was performed using the terms postpartum, infection, wound infection, puerperium, reason, risk factor, and their equivalent Persian words from 2010 to November 2019 regardless of publication status. RESULTS: Out of the 3227 studies obtained, 19 were reviewed after removing irrelevant articles, duplicates (shared in databases), and animal samples. Age, level of education, delivery method, presence of episiotomy, anemia due to postpartum hemorrhage, interventions and manipulations during childbirth, prenatal hygiene, Povidone Iodine usage before delivery to wash the vagina, antibiotic prevention, increased labor duration, obesity, and the presence of bacteria were common symptoms affecting postpartum infection. CONCLUSION: In this study, the factors affecting postpartum infection have been identified, some of which are avoidable. Identifying these factors helps reduce postpartum infections and their complications.

What can the early infection preventing pioneers teach infection prevention and control teams today?

BACKGROUND: Puerperal fever and erysipelas were common Streptococcal infections of the 18th and 19th centuries which caused extensive nosocomial outbreaks. With dramatic clinical presentations and high-mortality, physicians struggled to understand and prevent them. Three infection prevention and control (IPC) pioneers (Gordon, Holmes and Semmelweis) in the pre-antibiotic and pre-epidemiology era made significant discoveries. Although much has been written of their breakthroughs, this has been selective and at times misinterpreted. METHODS: The primary sources of the three IPC pioneers (1 translation) were reviewed to present 3 narratives of their discoveries. An interpretation of the pioneers' discoveries in the current context is provided. RESULTS: The IPC pioneers' achievements are much wider than acknowledged in extant hand hygiene guidance - in relation to the role of indirect contact transmission (environment and equipment), e.g. Semmelweis considered the primary measure to prevent infection to be the avoidance of contamination - not hand hygiene. CONCLUSIONS: The pioneers provided strong evidence of both direct and indirect transmission to significant 18th -19th century infections. They make a strong case for environment and equipment decontamination and cleanliness alongside decontaminating hands.

Características relacionadas à ocorrência de infecção puerperal em mulheres submetidas ao parto cesáreo / Characteristics related to the occurrence of puerperal infection in women submitted to cesarrel delivery

Objetivo: Este artigo de revisão sistemática tem como objetivo analisar as principais características relacionadas à infeção puerperal em mulheres submetidas ao parto cesáreo. Fonte dos dados: Foi realizada busca nas bases de dados on-line Biblioteca Virtual de Saúde (BVS) e PubMed. Seleção dos estudos: Selecionaram-se artigos publicados nos últimos 11 anos (2010-2021), totalizando 12 artigos analisados. Coleta de dados: Realizou-se a busca dos artigos a partir dos descritores infecção puerperal, mortalidade materna, cesárea, fatores de risco em inglês e português. Em seguida à adequação aos critérios de inclusão (artigos em inglês, português e espanhol, com publicação nos últimos 11 anos, realizados em humanos) e exclusão (artigos duplicados, revisão de literatura, estudos de caso e dissertações), a análise dos títulos e dos resumos dos artigos encontrados permitiu a exclusão daqueles que se afastavam do tema em estudo. Síntese dos dados: Dentre os fatores sociodemográficos, destacam-se mulheres nos extremos de idade, negras, residentes na zona rural, com baixo nível econômico e escolar, primíparas e tabagistas. Em relação aos fatores clínicos, obesidade, HIV, diabetes mellitus, doenças cardiovasculares, hipertensão arterial, pré-eclâmpsia e eclâmpsia, anemia e infecções geniturinárias apresentaram-se como fatores de risco para infecção puerperal. Fatores obstétricos também foram avaliados, identificando-se como variáveis importantes o parto cesáreo, rotura prematura de membranas, tempo de membrana rota, trabalho de parto maior que 12 horas, parto prematuro e trabalho de parto induzido, hemorragia pós-parto, transfusão prévia e mecônio em líquido amniótico. Por fim, as características assistenciais trazem o baixo número de consultas de pré-natal e número de toques vaginais antes e após a ruptura de membranas como variáveis de risco. Conclusão: Muitos dos fatores identificados são passíveis de controle, e a sua reversão contribui para a redução dos índices de infecção puerperal e, consequentemente, de mortalidade materna.(AU)

Objective: This systematic review article aims to analyze the main characteristics related to puerperal infection in women undergoing cesarean delivery. Source of data: A search was performed in the online databases Virtual Health Library (VHL) and Pub- Med. Selection of studies: Articles published in the last 11 years were selected, totaling 12 analyzed articles. Data collection: Articles were searched based on the keywords puerperal infection, maternal mortality, cesarean section, risk factors in English and Portuguese. Following the adaptation to the inclusion criteria (articles in English, Portuguese and Spanish, publication in the last 11 years, carried out in humans) and exclusion (duplicates, literature review, case studies and dissertations), the analysis of the titles and abstracts of the found articles allowed the exclusion of those who departed from the topic under study. Summary of the findings: Among the sociodemographic factors, women of extreme age, blacks, residents in the rural area, with low economic and educational status, primiparous women and smokers, stand out. Regarding clinical factors, obesity, HIV, Diabetes Mellitus, Cardiovascular Diseases, Hypertension, Pre-eclampsia and Eclampsia, Anemia and genitourinary infections were risk factors for puerperal infection. Obstetric factors were also evaluated, identifying as important variables cesarean delivery, premature rupture of membranes, ruptured membrane time, labor longer than 12 hours, premature labor and induced labor, postpartum hemorrhage, previous transfusion and meconium in amniotic fluid. Finally, the care characteristics bring the low number of prenatal consultations, the number of vaginal touches before and after rupture of membranes as risk variables. Conclusion: Many of the identified factors are possible to control and their reversion contributes to the reduction of puerperal infection rates and consequently maternal mortality.(AU)

Medical abortion offered in pharmacy versus clinic-based settings.

BACKGROUND: Medical abortion is usually offered in a clinic or hospital, but could potentially be offered in other settings such as pharmacies. In many countries, pharmacies are a common first point of access for women seeking reproductive health information and services. Offering medical abortion through pharmacies is a potential strategy to improve access to abortion. OBJECTIVES: To compare the effectiveness and safety of medical abortion offered in pharmacy settings with clinic-based medical abortion. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, four other databases, two trials registries and grey literature websites in November 2020. We also handsearched key references and contacted authors to locate unpublished studies or studies not identified in the database searches. SELECTION CRITERIA: We identified studies that compared women receiving the same regimen of medical abortion or post-abortion care in either a clinic or pharmacy setting. Studies published in any language employing the following designs were included: randomized trials and non-randomized studies including a comparative group. DATA COLLECTION AND ANALYSIS: Two review authors independently reviewed both retrieved abstracts and full-text publications. A third author was consulted in case of disagreement. We intended to use the Cochrane risk of bias tool, RoB 2, for randomized studies and used the ROBINS-I tool (Risk Of Bias In Non-randomized Studies of Interventions) to assess risk of bias in non-randomized studies. GRADE methodology was used to assess the certainty of the evidence. The primary outcomes were completion of abortion without additional intervention, need for blood transfusion, and presence of uterine or systemic infection within 30 days of medical abortion. MAIN RESULTS: Our search yielded 2030 records. We assessed a total of 89 full-text articles for eligibility. One prospective cohort study met our inclusion criteria. The included study collected data on outcomes from 605 women who obtained a medical abortion in Nepal from either a clinic or pharmacy setting. Both sites of care were staffed by the same auxiliary nurse midwives. Over all domains, the risk of bias was judged to be low for our primary outcome. During the pre-intervention period, the study's investigators identified a priori appropriate confounders, which were clearly measured and adjusted for in the final analysis. For women who received medical abortion in a pharmacy setting, compared to a clinic setting, there may be little or no difference in complete abortion rates (adjusted risk difference (RD)) 1.5, 95% confidence interval (CI) -0.8 to 3.8; 1 study, 600 participants; low certainty evidence). The study reported no cases of blood transfusion, and a composite outcome, comprised mainly of infection complications, showed there may be little or no difference between settings (adjusted RD 0.8, 95% CI -1.0 to 2.8; 1 study, 600 participants; very low certainty evidence). The study reported no events for hospital admission for an abortion-related event or need for surgical intervention, and there may be no difference in women reporting being highly satisfied with the facility where they were seen (38% pharmacy versus 34% clinic, P = 0.87; 1 study, 600 participants; low certainty evidence). AUTHORS' CONCLUSIONS: Conclusions about the effectiveness and safety of pharmacy provision of medical abortion are limited by the lack of comparative studies. One study, judged to provide low certainty evidence, suggests that the effectiveness of medical abortion may not be different between the pharmacy and clinic settings. However, evidence for safety is insufficient to draw any conclusions, and more research on factors contributing to potential differences in quality of care is needed. It is important to note that this study included a care model where a clinician provided services in a pharmacy, not direct provision of care by pharmacists or pharmacy staff. Three ongoing studies are potentially eligible for inclusion in review updates. More research is needed because pharmacy provision could expand timely access to medical abortion, especially in settings where clinic services may be more difficult to obtain. Evidence is particularly limited on the patient experience and how the care process and quality of services may differ across different types of settings.

[A study of the incidence of nosocomial infections and the associated risk factors in the city of Mbujimayi, Democratic Republic of Congo]. / Etude de l´incidence des infections nosocomiales et facteurs de risque dans les maternités de la ville de Mbujimayi, République Démocratique du Congo.

INTRODUCTION: this study aims to determine the incidence of nosocomial infections and the associated risk factors in new mothers and newborns at the maternity wards in the city of Mbujimayi, Democratic Republic of the Congo. METHODS: we conducted a longitudinal descriptive study of the incidence and risk factors for nosocomial infections in patients without them at baseline in 231 maternity units. Data were collected on a weekly basis over a period of 6 months. Simplified WHO criteria were used for data collection. They are useful for hospitals that do not have advanced diagnostic techniques. RESULTS: the overall incidence of nosocomial infections in new mothers was 24.8% and 22.3% in newborns. The significant risk factors for nosocomial infections in new mothers and newborns were instrumental maneuvers (p=0.005; OR=2.7; 95% CI [1.3-5.4]), emergency cesarean section (p=0.000; OR=2.3; 95% CI [1.7-3.9]), the use of the same eye-drop bottle in all babies (p=0.004; OR=2.7); 95% CI [1.4-5.5]) and preterm baby care outside an incubator (p=0.000; OR=2.61; 95% CI [1.73-3.92]). CONCLUSION: repeated incidence (or lack of prevalence) surveys are essential to assess the effects of information, awareness and training programs implemented to control hospital acquired infections.

Postpartum endometritis after uterine cleaning versus no cleaning in cesarean sections: Randomized clinical trial.

AIM: The aim of the study was to compare the rates of postpartum endometritis due to uterine cleaning and no cleaning in patients delivered by elective cesarean section. METHODS: This was a randomized clinical trial conducted at the Obstetrics and Gynecology Department, Suez Canal University Hospital, Ismailia, from June 2019 to November 2019. We recruited patients undergoing cesarean delivery aged 18-45 years with singleton pregnancy, intact membranes, either first or repeated delivery, without labor pains. Patients were allocated into two groups, uterine cleaning (336 patients) and no cleaning (312 patients). The main outcome measure was the occurrence of postpartum endometritis. RESULTS: Both groups were matched in their demographic characters. Twelve patients (3.6%) developed endometritis in the cleaning group versus one patient (0.3%) in the other one. Estimated blood loss was 754.35 ± 247.13 and 730.36 ± 232.77 for the cleaning and no cleaning groups, respectively, with a P value of 0.201. Septic wound infection (21 patients, 6.3%) was predominant in the cleaning group. CONCLUSION: Uterine cleaning after delivery of the placenta during CS can be omitted as a surgical step during the operation. It was associated with increased rates of postpartum endometritis and blood loss.

Using the new definition of intraamniotic infection - is there morbidity among the women left out?

BACKGROUND: Recently, ACOG released updated definitions for intraamniotic infection (IAI): maternal fever (≥38.0 °C) and ≥1 symptom (fetal tachycardia, maternal white blood cell count >15,000/mm3 or purulent discharge). Treatment was no longer recommended for women with fever <39.0 °C plus maternal tachycardia or fundal tenderness (previous criteria). The objective of this study was to compare postpartum infectious morbidity among women meeting previous criteria (but not the new IAI criteria) to women meeting new IAI criteria. METHODS: Retrospective cohort of women delivering vaginally at a single academic center. Demographics, antepartum and intrapartum characteristics of women who met diagnostic criteria for chorioamnionitis (previous criteria) compared to those who met IAI criteria using bivariate statistics. The primary outcome was a composite of postpartum infection, including: endometritis, perineal infection, sepsis, urinary tract infection, pyelonephritis. Backward-stepwise elimination used to estimate odds of primary outcome. RESULTS: Of 229 women who met previous IAI criteria, 51 (22.3%) did not meet new IAI criteria. Women no longer meeting IAI criteria were younger (25 versus 27 years, p = .02), more likely to have gestational hypertension (16.0 versus 3.4%, p < .01), and less likely to have third or fourth degree lacerations (2.0 versus 13.4%, p = .02). No difference in antibiotic receipt was observed. Postpartum infection occurred in 16/229 (7.0%) women overall; five (9.8%) in those not meeting new IAI criteria, and 11 (6.2%) meeting new IAI criteria. After adjusting for confounders, there was no difference in odds of postpartum infection (aOR 1.65, 95% CI 0.55-4.99). CONCLUSIONS/IMPLICATIONS: Among women who met old ACOG criteria for IAI, but not the new criteria, postpartum infection occurred in nearly 10%. This number could be higher if these women were not treated with antibiotics.

Genetic evolution of invasive emm28 Streptococcus pyogenes strains and significant association with puerperal infections in young women in Finland.

OBJECTIVES: Streptococcus pyogenes or group A streptococcus (GAS) is a human specific pathogen that annually infects over 700 million individuals. GAS strains of type emm28 are an abundant cause of invasive infections in Europe and North America. METHODS: We conducted a population-based study on bacteraemic emm28 GAS cases in Finland, from 1995 to 2015. Whole-genome sequencing (WGS) was used to genetically characterize the bacterial isolates. Bayesian analysis of the population structure was used to define genetic clades. Register-linkage analysis was performed to test for association of emm28 GAS with delivery- or postpartum-related infections. A genome-wide association study was used to search for DNA sequences associated with delivery or puerperal infections. RESULTS: Among 3060 bacteraemic cases reported during the study period, 714 were caused by emm28. Women comprised a majority of cases (59 %, 422/714), and were significantly over-represented (84.4 %, 162/192, p < 0.0001) among cases in the childbearing age group (20-40 years). Register-linkage analysis revealed strong association (p < 0.0001) of emm28 bacteraemias with delivery and puerperium. In this register-linkage analysis, 120 women with GAS bacteraemia were identified and linked to delivery, infections during delivery or puerperium time. Among these the proportion of cases caused by emm28 was significantly higher than any other emm type (55.8%, 67/120, p < 0.0001). Among the four genetic subclades identified, SC1B has dominated among the bacteraemic cases since 2000. Altogether 620 of 653 (94.9%) isolates belonged to SC1B. No specific sequence or genetic clade was found nonrandomly associated with delivery or puerperal infections. CONCLUSIONS: Women of childbearing age were significantly overrepresented among bacteraemic emm28 GAS cases, and in particular were strongly associated with delivery and puerperium cases over the 21 years studied. The molecular mechanisms behind these associations are unclear and warrant further investigation.
